본 발명은 휠베어링의 베어링이너씰을 제거하여 드래그 토크를 저감하는 한편, 부트의 주름부분에서 발생하는 마찰소음을 저감하도록 한 드라이브 액슬 조립체에 관한 것으로, 본 발명에서는, 휠하우징에 조립되는 휠베어링; 링 형상으로 형성되고, 외경부가 휠베어링의 외륜에 고정되는 아우터링; 일단의 대경부가 상기 아우터링의 내경부에 조립되는 부트; 및 상기 부트 타단의 소경부와 드라이브샤프트 사이에 조립되어 부트의 회전을 제한하면서 이물질 유입을 방지하는 베어링씰유닛;을 포함하여 구성되는 드라이브 액슬 조립체가 소개된다.

    The present invention relates to a drive axle assembly which removes a bearing inner seal of a wheel bearing to reduce drag torque and reduces a friction noise generated from a corrugation portion of a boot. The present invention comprises: the wheel bearing assembled to a wheel housing; an outer ring, where an outer diameter unit is fixated to an outer wheel of the wheel bearing, formed in a ring shape; the boot where a large diameter unit of one end is assembled to an inner diameter unit of the outer ring; and a bearing seal unit assembled between a drive shaft and a small diameter unit of the other end of the boot to restrain rotation of the boot and prevent introduction of a foreign substance.
